HEMI MDS questions

Diablo isnt as friendly for the trucks as it is the cars.
Theres no switch you can add to easily enable/disable it...the best/only way is through your programmer.
I too have Diablo on my car (MagnumRT) but chose SCT for the truck (04 Ram)...its alot less finickey.

And yes, 06 is the first year for MDS on the trucks. 05 was for the cars (all of em had MDS)
